The 31-year-old's short-term contract expires in January, meaning he could leave the club for free.

Leeds are keen to keep hold of the ex-Liverpool forward, who has impressed during his time in the npower Championship, scoring five times in his 22 appearances, and have opened talks with the player's representatives.

His agent Willie McKay told the Daily Mail: "We have spoken to the chief executive Shaun Harvey and we hope to have something sorted soon."
